+  method: "POST",
+  body: JSON.stringify({ messages, user_type }),
+});
+const data = await response.json();
+// Manual message handling
+```
+
+**After:**
+```typescript
+// AI SDK with streaming
+const { messages, input, handleSubmit, isLoading } = useChat({
+  api: "/api/chat",
+  body: { userInfo },
+});
+// Automatic message and state management
+```
+
+### 2. Streaming Support
